The framerate does not show with this firmware when playing a film which it did in the 1.6 firmware,so no instant check if correctly played. Also with this new firmware do you have to have the 24HZ switched to off in the Settings as in the previous firmware? Also new firmware installed as recommended make sure you turn the volume control on the handset to max (use the volume control on the amp or processor for best results) as it gets reset during the new firmware installation
FPS display was only a feature of the beta himediaplayer app, never official 1.6.
Ultimately, it might have looked like a good feature but all it was doing was reporting what himediaplayer thought fps was. In the case of FW 1.0.6 and earlier this would have correctly reported FPS but still HDMI Hz output was incorrect. The best way to determine what fps is being output is through the info display of your TV / projector.
The good news is that after some initial testing I think FPS mismatch / microstutter bug is fixed in 1.0.7. Certainly the usual test videos play without the frame skips. More testing welcome, but for 23.976 and 29.970 I think 1.0.7 is smooth. That's with 24p mode turned on.
